2 Claims.

This invention relates to metal window sashes, and has reference more particularly to window sashes adapted for either top opening or bottom opening ventilation.

In the manufacture of metal basement sash or other window sash, it is found desirable to provide for either top ventilation or bottom ventilation to suit the desires of the user. Considerable trouble has been experienced with metal sash previously marketed in that the sashes were unhandy to open or close. Difficulty has also been experienced in that rain is found to leak through parts of the sash. The metal sash previously offered have also been characterized by high manufacturing costs.

An object of the invention is to provide a metal window sash having provision for top or bottom ventilation depending on the needs and desires of the user.

Another object of the invention is to reduce dealers inventories by providing a single type of sash which may be used for top or bottom ventilation without structural change.

Another object of the invention is to provide a sash of the character indicated which may be conveniently operated by the user.

A further object of the invention is to provide a metal sash which excludes all rain.

A still further object of the invention is to provide a metal basement or other sash which will be comparatively low in manufacturing cost; also to improve window sashes in other respects hereinafter specified and claimed.

Reference is to be had to the accompanying drawings forming a part of this specification, in which Fig. l is a rear elevation of my improved window sash mounted upright for top ventilation,

Referring to the drawings by numerals, a window casing i5 is substantially U-shaped in cross-section and is composed of a web it. a short inner leg or flange H and a longer outer leg or flange ill. The casing 15 is formed into a rectangle of individual rails welded together at the corners. The legs H and !3 form a watertight drain channel l9 which receives any rain which might leak into said channels. Weep holes or drain holes are formed in the legs 18 closely adjacent the webs of the upper and lower rails so that any water collected in any part of the channel It may drain to the lower rail and then through the lower rail weep holes to the outside. A metal angle 22 is spot welded to the outside of each horizontal channel web l6, said angle 22 having an outstanding leg 23 which'is arranged to engage in a groove 24 of a masonry wall 25, being secured in said groove 2 by grout or mortar 25. The web 21 of a channel is spot welded or otherwise secured to the outside of the vertical webs it. A short leg 28 extends outwardly from the web 2?, and a longer leg 29 also extends outwardly from said web 21. The leg 29 engages in the groove in wall 25 and is mortared into place by grout 26.

A ventilator frame M is in general Z-shaped inside of flanges 3t and 34 and window glass is positioned against said strips 39 in the frames. Headed studs are secured to webs 32 and 31 and angle clips 42 have inclined slots 43 to en'- gage the studs ti and press the glass 40 against the sealing strips 3% so as to make a weathertight puttyless joint. Flanges ll contact with flanges 33 and flanges 58 contact with flanges 34 so as to provide a double weathertight seal between the ventilator frame and the window casing.

In order to hingedly connect the ventilator frame with the window casing, I provide a pair of hinges 45 having a U-shaped leaf 4% engag ing over the flange l! and welded to the web'ifi,

and an L-shapedleaf 4? which is welded to the inside of web 32. A slot 48 is formed in the Pressed cork of the arm flange 33 to give clearance for the hinge leaves 46 and 41. A hinge pin 49 connects the hinge leaves 46 and 41. A latch handle 51 is pivotally connected to the inside of web 32 by a hinge pin 52, said handle having an outwardly extending latch flange 53 which engages behind a latch stud 54 which extends from the inside of web I6 so as to lock the ventilator frame firmly in closed position. A shallow slot 55 is formed in the flange I! to give clearance for the latch flange 53. A cup-shaped member 55 is secured in place between latch handle 5| and frame by pin 54 so as to cause any accumulation of Water on web I6 to drain out through weep holes 23 without overflowing through said slot when the window is positioned with the latch at the bottom.

One of the salient features of my invention comprises a guide arm 51 which is hingedly connected at one end by pin 58 to the ventilator frame web 32. The opposite end of said arm 5'! is provided with an outwardly extending headed stud 59 which engages in a slot 60 formed in a guide strip El. The strip BI is provided with offset flanges 62 at each end which are secured in spaced relation, as by welding, to the inside of window casing web It. In order to provide a window which may be installed for top or bottom ventilating as desired, the slot 50 is formed with a plurality of pairs of opposed shoulders 63 and 64. When the window is mounted for top ventilation (Fig. I), the stud 5S engages one of the shoulders 64 to support the ventilator frame in open position with the desired amount of ventilation. When the window is mounted in inverted position (Fig. 11) for bottom ventilation, the stud 59 engages one of the shoulders 63 to support the ventilator frame. The stud 59 is brought into engagement with shoulders 63 or 64 as the case may be, by manual actuation It will be seen that the ventilator is extremely simple and handy to operate. The window structure disclosed is especially useful as it provides for either bottom or top ventilation without structural change by simply mounting the window frame in the desired position. Dealers need only carry a single type of sash in stock for either top or bottom ventilation, where heretofore it was necessary to carry two types of sashes in stock, thus doubling dealers inventories.

As shown particularly in Fig. 14, all of the frame adjusting mechanism, including the stop arm 51 and cooperating strap 6!, are completely enclosed in the space between the casing and l the frame. Also the strap 6! is entirely within the casing channel 15, and, when the frame is opened, the stop arm 5'! moves outwardly from the enclosure through the space between the narrow casing flange I1 and the web 32 of the frame. By this construction a double weather seal is maintained by the cooperating flanges and the mechanism is completely hidden when the frame is closed and a more sightly appearance is provided.

The outwardly extending flange 35 which extends completely around the frame provides top and side bafiles to draw moisture away from the glass when the window is mounted for either top or bottom ventilation and at the same time the bottom rail flange functions as an overhanging baflle to protect the weather seal between the lower rails of the frame and casing. The outer weather seal and the drain channel are so related that all moisture which may leak through the seal will be directed into the drain channel and discharged from the weep holes in the lower rail irrespective of which horizontal rail is uppermost.

I would state in conclusion that, while the i1- lustrated example constitutes a practical embodiment of my invention, I do not wish to limit myself precisely to these details, since manifestly the same may be considerably varied without departing from the spirit of the invention as defined in the appended claims.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. In a reversibly mountable basement sash, a channel-iron casing having inturned flanges with the front flange materially wider than the rear flange, a metal frame in said casing and having portions cooperating with both casing flanges to form a double weather seal with a substantially continuous drain chamber therebetween, said frame being hinged to one of the horizontal rails of said casing for either top or bottom ventilation, depending on the mounting of the sash, a latch pivotally mounted on the opposite rail of said frame, a stud on said channel iron for locking engagement by said latch, the rear flange of said casing being cut away to receive said latch therethrough and a drainage baflle in said channel around said stud and latch and closing the cut-out in said rear casing flange and forming a wall of said drainage channel, the outer flange of both horizontal rails of said casing having-drainage perforations closely adjacent the web of said channel iron to provide bottom drainage when said frame is mounted in either of its reversible positions.

2. In a reversibly mountable basement sash, the combination with a rectangular channeliron casing of uniform cross section having inturned flanges, the front flange being materially wider than the rear flange to form a frame stop, a Z-bar frame of uniform cross section in said casing and having its outturned rear flange overlapping the rear flange of said casing, the web of said Z-bar frame being spaced from the edge of said rear casing flange toprovide a narrow space therebetween, and the front flange of said casing overlapping the inturned front flange of said Z-bar frame to form a double weather seal with a continuous drain chamber therebetween, said frame being hinged to said casing for either top or bottom opening, depending upon the mounting of said sash, of means normally completely enclosed within said double sealed drain chamber to support said frame in open ventilating position when said sash is mounted in either reversible position, said supporting means comprising a member secured in said channel and having an elongated slot therein of tortuous contour forming oppositely facing abutments in the respective opposite edges of said slot, and a rigid link having one end pivoted to the web of said Z-bar and the other end provided with a stud slidably engaged in said slot, said link' extending through the space between said web and the narrow inturned rear flange of said channel when said frame is open, said stud co-operating with the abutments in a related side of said slot to positively support said frame on a correspondingly facing abutment and in a partially opened position when said sash is mounted in either of its reversibl positions.
